“I looked at this map and thought, hmmm…where have I seen this divide before? Looks very familiar. This isn’t just some urban/rural, professional/worker, white-wine-and-brie/beer-and-sausages thing!”
Mr Hecht did some overlay work, and came up with this remarkable fit: “The divide between the (more free-market) PO and the (more populist) PiS almost exactly follows the old border between Imperial Germany and Imperial Russia, as it ran through Poland! How about that for a long-lasting cultural heritage?!?”
I expect those more familiar with Polish history would not find this surprising, in the same way that I don't find this map surprising at all:
I believe it was William Faulkner who said, "The past is not dead. In fact, it's not even past."
